Outdoor air pollution has been related to adverse respiratory effects since the 1930s.
The project “Air Pollution and Health: a European Approach” (APHEA 1996) has confirmed that air pollution increases daily cardiorespiratory mortality.
Increases in the concentration of particulate matter in the air are linked to an increase in the risk of death from respiratory diseases. Increases in the concentration of particulate matter, black smoke and sulphur dioxide in the air are associated with emergency hospital admissions.
Deaths from outdoor pollution
A study published in 2000 and carried out in three countries (Austria, France and Switzerland) concluded that outdoor pollution was the cause of 6% of the total number of deaths in these countries.
